Indicator C3 — Duplicate or Near-Duplicate Projects

AI-verified / Na-verify ng AI Data as of October 21, 2026

Duplicate or Near-Duplicate Projects

Very similar descriptions within ~100m or identical coordinates across contracts/years.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: contracts 23GA0103 and 24GA0133 have near-identical descriptions about 43 m apart (funding years 2023, 2024; ₱29.40M, ₱28.95M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, or covers an adjacent section not clearly labeled.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both refer to the construction of a revetment wall along the Aklan River at (Brgy./Barangay) Palale, Banga, Aklan, with no distinguishing phase, package, section, or site markers. The only differences are minor wording ('Flood Control' and 'Barangay' vs 'Brgy.'), which are not distinguishing per the rules. The projects are about 43 meters apart and funded in consecutive years, which fits the pattern for possible duplicate or overlapping works. All required records and fields are present.
